Current Measurement Device Design Based on MSP430 Single-Chip Microcontroller

To measure high-current, contacting with the wire directly is a certain danger. This article describes a pincer current transformer what the principle of electromagnetic induction be used in, using non-contact of the current measurement methods. In addition, the current strength meter site may not be the city´s conditions. In this paper, CPU used in this design of instruments is made by the U.S. company Texas Instruments, msp430f437, which is An ultra-low power microcontroller and Particularly suitable for battery-powered or hand-held device.
